Poster #30

Internet ratings data are usually ordinal measurements nfrom 1 to 5 (or 10) rated by Internet users on the quality nof all kinds of items. The traditional graphical displays nof the ratings data does not account for the inter-rater difference.nSome model-based methods with MCMC approach have beennsuggested to address this problem.nIn the present work we propose a real-time Bayesian inferencenalgorithm for parameter estimation.nTwo real data sets and the R implementation of the abovenmentioned algorithm will be presented.
